Letters .Patent No. 94,059, dated August 24, 1869.

IMPROVEMENT IN TAPS FOR OIL-VESSELS.

The Schedule referred to in these Letters Patent and making part of the same To all whom lit may concern:

Be it known that/I, MATTHEW ANDREW, of Melbourne, in the colony of Victoria, Australia, have invented certain new anduseful Improvements in Vessels for containing Oil or other Liquids, and .in

devices for drawing the contents from the'salne; and- I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, forming a part of this specification.

lhese improvements relate mainly to providing vessels containingoil or other liquid with devices which I call capsule-taps, which are constructed and attached drawlng.

A hole is cnt in any suitable part of the vessel a, in the ordinary manner, through which hole the said vessel is filled with the oil or other liquid.

A cap orcover, l1, is soldered over this hole, and a central hole is pierced in the said cap.

In this hole is inserted a tube or pipe, c,fslightly smaller' in external diameter than the hole, but ot' sut'- ticient diameter to serve as a tap.

The inner end of this tube or pipe is `essed somewhat open', for the purpose of preventing its being withdrawn more than a certain distance. A

Near this end of the tube a hole, cl, is made in the side thereof, for the passage of the liquid to be drawn from the vessel a.

The tube'c is jtted within a box-tube or socket, d,

which has a cork, leather, or other lining, f1.1, extending for a short distance from the open end thereof, and made to tit tightly round the tube c.

In the side of this box-tube d is a hole, d2, which also extends through the cork or other lining d* thereof, and which corresponds with the hole c1 in the side ot' the small tube c, so as to permit the-free passage of the contained liquid when the said small tube is properly drawn forward, asl shown in iig.'2.

The outer end of the said box-'tube is sloped or bevelled in such a manner, that when it is soldered to the cap or cover b, it forms a slight angle therewith.

The tube c has a hole, c2, at its outer end, and this hole should he Iliade at the under side of the said tube, as shown, to allow the liquidto pass through it and escape in a downward direction, when the tube c is drawn out toits full extent.

When the tube is pushed in, `the holes c1 and d2 are closed, and the ingress of the liquid t'o the box-tube is stopped. 1

The tube c has fastened. to its outer end a ring, c",

which'forms a convenient said tube.

The cap or cover b thus provided with thev boxf tube d, containing the smaller tube c, forms at once a capsule and a tap, and as a means of protection to the means for drawing out the said tap, to prevent its being opened before the ves-A sel c reaches its final destination, the smaller Atube c is pressed in with the small flange ci, resting upon the cover l), the ring c, which is formed with a hinge or joint for the purpose, is turned down and laid dat upon the said cover, and a thin piece of brass or otherv metal, e, is soldered over the face ofthe cap or cover b. When the vessel alias been filled-'with the oil or other liquid, andv it is desired to close the same, the

cover b ot' the capsule-tap has shnplyvto be soldered upon the hole cut in the saidA vessel, and when required, the tap is made available by removing the piece e of brass or other metal soldered `on thev face4 of the said capsule-tap.

In the lnodiiication of my invention, illustrated in figs. 3, 4, and 5, the small tube c, which is made of brass, copper, tin, glass, porcelain, or any other suitable material, is L-shaped, the upright portion, from 'l to 2, being preferably about one and one-half inches long,an,d the horizontal part, from l to 3, about threequarters of an inch, and its diameter being suitable for drawing off the oil or other liquid from .thevesseL The hole c1 is made in the side of the-horizontal pait of this tube, at an angle to the upright portion'A of the tube of about eighty degrees, to admit the liquid to low through the said'tuhe. p

The cork, or other suitable lining d, is fitted closely around the horizontal part ofthe tube, and within the external tube or socket d, which is made of tin or any7 other convenient material, so as exactly to cover the cork or other lining.

In the centre ot' this external tube or socket, and' also in the cork. or other lining, is made the hole d?, which corresponds in size and position with the hole c, in the side of the horizontal part of the tube c.

The cap or cover b is depressed or indented in such" a way that the tube c, wheirformedas above described, will conveniently lie therein, a suicient margin, b1, around being left not depressed by which it can be 'soldered over the hole cut in the tin or other vessel a for filling the same.

In this cap or cover a hole is made, exactly corresponding in `position with thehole already described A in theexternal tube d.

The horizontal tube being laid in the depressed or indented part of the cap or cover 1), the external tube l is soldered to the said cap or cover, or otherwise firmly fixed thereto, but in such a way that the holes should coincide.

' Y'lhe tube c has a hole c2. made at its outer end inA such a position as to giveethe liquid, at its exit, a downward direction, as shown in iig. 4.

XVhen the tap .is turned back within the recess it will have no part projecting above the surface ofthe cover b, and I then solder, or otherwise secure, over the said recess or indented portion of the cap, the thin piece c of brass or other metal, as hereinbefore described.v

Y The capsule-tap can thenbe attached to the can or other vessel a, by being soldered over the hole-made for lling the same, and whenit is desired to 'draw the contents from the said vessel, the thin piece of metal can'b(l readily removed and the tube cturned into theposition shown in vfig. 4,-the holes in the tubes being thereby made to communicate with each other and permit the lliquid to escape.

I do not confine myself to the precise form or construction'of ,these capsule-taps 'herein described and illustrated, as they may be varied within certain limits,

-but they must always be adapted to the main object of my invention, which is to secure oil or other liquid pose of a tap to draw off' thcjcontained liquid, without would interfere with the convenient packing of the same for transportation.

W'hat I claim as my invention,ai1d desire to secure by Lettersilatent, is

y 1. 'X capsule-tap, consistingr of the cap or cover b, the adjustable tube c, andouter tube or socket (Z, the said tubesbeiug provided with cork or other suitable ranged to be opened and closed by the adjustment of the tube c, which is formed and arranged to leave no v part projecting beyond the cover b,and is secured by a thin plate or sheet of metal, c,A all substantially as and for thepurposes set forth. v i

2. A can or vessel brcontaining. oil or 'other liquid, provided with one ofthe capsule-taps, substantially as set forth. Y
